Faced with financial trouble, the Pennsylvania Railroad decided in the early 1960s to tear the grand old station down ... and build an office tower and a new Madison Square Garden in its place.

Architects and others protested the plan ... to no avail.

Demolition began in 1963, and after three heartbreaking years, Penn Station was reduced to what it remains today ... a windowless subterranean remnant of its former self.

On a more positive note, Penn Station's destruction helped inspire the landmarks preservation movement, which has saved Grand Central Terminal and other famous New York City structures from tampering ... or worse.
